Objective To understand the effect of the three-cell latrine and B-type tilted ellipsoid methane tank for eliminating eggs of schistosome in different seasons and temperatures in order to evaluate their values for popularization and application in schistosomiasis endemic areas.Methods The eggs of schistosome collected from infected rabbits were put into the three-cell latrines and methane tanks in different seasons.The miracidia were observed and counted after collecting the eggs for hatching experiments on the 5th,10th,15th,20th,25th,30th,40th,50th,and 60th day,respectively.Results In the three-cell latrine,the time of eliminating eggs completely in the fecal residue in winter,spring(autumn),and summer was 50,30,15 days,respectively,and the time of completely eliminating 100 eggs of schistosome was 40,20,10 days,respectively.Correspondingly,in the methane tank,the time of eliminating eggs completely in the fecal residue in winter,spring(autumn),and summer was 30,15,10 days,respectively,and the time of completely eliminating 100 eggs of schistosome was 20,15,5 days,respectively.Conclusions The three-cell latrine and B-type tilted ellipsoid methane tank could effectively eliminate schistosome eggs in human and animal excreta and achieve the national hygienic standard on night soil in the endemic areas of Jiangxi Province.
